The family divvied up Miguel Santiago’s ashes after his cremation and stored them in the vials, which they would sometimes wear on necklaces in his memory.

“He wanted for his grandkids to have a piece of him, and his children, me and my mother, nephew and son,” Nelson Santiago said of his dad, who once owned a pizzeria in Brooklyn.

Cops conducted the raid in connection to allegations one of Santiago’s grandsons was involved in a gun sale. They charged the grandmother, one of her sons and two grandsons with possession of a controlled substance and ammunition.

The family denied the accusations, including the gun sale, and said the ammo was a few old bullets that Miguel had kept in the house.

Making it worse was the NYPD’s refusal to return the ashes, said Nelson Santiago.

The family fears the ashes have been trashed.

Nelson Santiago said the family was told that “evidence they don’t use is discarded. We don’t know where my dad is at. We’re going on a year.”

The city will review the complaint, a Law Department rep said.

The NYPD said they were at Lucia Santiago’s home executing “a legal search warrant,” and that drugs seized during any raid can’t be returned “because they cannot be legally possessed.”

Police did not say whether the substances taken from the Santiagos were confirmed to be heroin, but said people seeking the return of legal items can get a release from the district attorney’s office and then claim their belongings from the city’s property clerk.
